Bitunicate asci have an inner wall that balloons out from the outer wall prior to ascospore discharge, and in unitunicate asci the wall layers do not separate from every other. A wide variety of fruiting bodies are formed by members of subphylum Pezizomycotina, such as cleistothecia, chasmothecia, apothecia, perithecia and pseudothecia. Stromata, hardened masses of hyphae on or in which perithecia or pseudothecia are formed, happen in some members of this subphylum.
